类名称：XYBlockRenderer

XYBlockRenderer介绍

[英]A renderer that represents data from an XYZDataset by drawing a color block at each (x, y) point, where the color is a function of the z-value from the dataset. The example shown here is generated by the XYBlockChartDemo1.java program included in the JFreeChart demo collection:
[中]一种渲染器，通过在每个（x，y）点绘制颜色块来表示XYZDataset中的数据，其中颜色是数据集中z值的函数。这里显示的示例由XYBlockChartDemo1生成。JFreeChart演示集合中包含的java程序：
